! 38: usage="Usage: $program [OPTION]... FILE...
! 39:
! 40: Run each Texinfo or LaTeX FILE through TeX in turn until all
! 41: cross-references are resolved, building all indices. The directory
! 42: containing each FILE is searched for included files. The suffix of FILE
! 43: is used to determine its language (LaTeX or Texinfo).
! 44:
! 45: Makeinfo is used to perform Texinfo macro expansion before running TeX
! 46: when needed.
! 47:
! 48: Operation modes:
! 49: -b, --batch no interaction
! 50: -c, --clean remove all auxiliary files
! 51: -D, --debug turn on shell debugging (set -x)
! 52: -h, --help display this help and exit successfully
! 53: -o, --output=OFILE leave output in OFILE (implies --clean);
! 54: Only one input FILE may be specified in this case
! 55: -q, --quiet no output unless errors (implies --batch)
! 56: -s, --silent same as --quiet
! 57: -v, --version display version information and exit successfully
! 58: -V, --verbose report on what is done
! 59:
! 60: TeX tuning:
! 61: -@ use @input instead of \input; for preloaded Texinfo
! 62: -e, -E, --expand force macro expansion using makeinfo
! 63: -I DIR search DIR for Texinfo files
! 64: -l, --language=LANG specify the LANG of FILE (LaTeX or Texinfo)
! 65: -p, --pdf use pdftex or pdflatex for processing
! 66: -t, --texinfo=CMD insert CMD after @setfilename in copy of input file
! 67: multiple values accumulate
! 68:
! 69: The values of the BIBTEX, LATEX (or PDFLATEX), MAKEINDEX, MAKEINFO,
! 70: TEX (or PDFTEX), and TEXINDEX environment variables are used to run
! 71: those commands, if they are set.
